Dog's with Cancer - How Nutritional Support can Increase Their Lifespan

By Helga Schmitt

A key role in the prevention, control and treatment of malignancies in dogs has clearly been pointing to the nutrients which they receive in their diets. It has finally become accepted by many health care professionals, that nutrients are certainly a large part of the treatment protocol for preventing cancers.

Many micro nutrients are extremely effective when combined with traditional therapies such as surgery, chemotherapy, radiation therapy, and biologic responsive modifiers. Any nutrient that is used in conjunction with anticancer therapies is called adjuvant therapeutics.

Cachexia is a metabolic consequence of cancer that is extremely important. This is a progressive involuntary weight loss that occurs even despite adequate nutritional intake. Any dog that has this, ends up with a decreased response to treatment and shortened survival time. Before any clinical signs of Cachexia are even noticed, the metabolic alterations have already occurred.

There are three phases of cancer cachexia. The first is silent and the dog does not exhibit any outward signs of the disease but the biochemical changes and alterations in amino acids are present. During the second phase the dog will start to lose weight, appear anorexic and lethargic. In the third phase, the dog has marked debilitation, weakness and is losing carbohydrate and protein stores in the body.

The alterations in metabolism combined with the physical effects of the cancer, are withering away at the entire dog. Dogs with cancer have a significant metabolic alteration in carbohydrate metabolism. Diets high in simple carbohydrates can increase the amount of lactate produced. The host then uses this excessive energy for the conversion of lactate. Long-term and harmful effects are placed on the dog from excessive lactate.

The host becomes compromised from the cancer feeding off of the carbohydrates. There is a tendency for tumors to manifest amino acids for their energy source via glycogens. Numerous body functions are influenced by these changes. The immune response, gastrointestinal function and surgical healing is the most upset by these alterations.

We now have a competition going on between the host and the cancer cells for the amino acids. If there is not a sufficient amount, the cancer will take them from the host. High value proteins need to be supplied. To help the host and reduce the gastrointestinal toxicity for dogs with cancer, amino acids like arginine and glutamine really assist and support the immune system.

Loss of fat causes most of the weight loss in dogs with cancer cachexia. Dogs with cancer will benefit from reduced simple carbohydrates and increased fat in their diets. Alterations in the dog with cancer can be minimized with the addition of N-3 fatty acids in their diets. The adverse effects of radiation are reduced by these as well as them having an anticancer effect.

Each dog with cancer needs to be assessed individually to determine the appropriate amount and type of nutrients that they should receive. Retinoids have the ability to regulate cancer cells. Various studies have determined that these agents are beneficial either as a stand alone or in combination with other agents in the treatment of certain types of malignancies.

Vitamin C has the most potential in preventing malignant disease as well as in treating certain cancers. Vitamin C could be an alternative for overcoming drug resistance in certain cancer cells. It has been known to prevent cancers of the esophagus and stomach.

One of the great capabilities of Vitamin E is its tendency to block mammary tumors and colon cancer. In the makeup of Vitamin E, it has chemo-preventative properties which work against various malignancies. In studies that were done on dogs, it was shown that some had a complete remission in cancer and others had a 50% reduction in tumor size.

Also suggested as chemo-preventive or anticancer agents are the minerals; copper, zinc, magnesium, calcium, lead, iron, potassium, sodium, arsenic, iodine, germanium and selenium. In addition to these, numerous amino acids have been used for inhibiting tumor growth.

For treating lymphomas and leukemia in dogs, the enzyme L-asparaginase has been helpful. For animals that have been exposed to carcinogens, garlic extracts have anticancer qualities.

Avoid preservatives, additives and chemicals in your dog's food. Give them a holistic diet that is full of fresh foods and supplements, to support their body and reduce their chances of getting cancer. If they do get cancer, it will reduce the shock on their body. Give to them daily, anticancer herbs like green tea or turmeric.

Recognize the signs of cancer: a fussy appetite, lumps and bumps, weight loss, sores that won't heal, odors, lethargy, difficulty breathing, stiffness or soreness, loss of enthusiasm, difficulty urinating or defecating, and persistent discharges.

It is very important to greatly reduce the carbohydrates in the diet and to increase with fats and proteins. The best fats to add are fish oil (preferably salmon) and cold pressed flax oil. Some anticancer foods are beetroot, broccoli, parsley, berries, apples, pears, peaches, plums, cabbage, sage, garlic, yams, cauliflower, shitake mushrooms, green and orange vegetables, yogurt, fish, carrots, watermelon, spleen, fresh thymus and extracts. Feed approximately 60% meat and 40% vegetables.

Include in your dog's diet Vitamin C, Vitamin E, Co enzyme Q10, Omega-3 fatty acids, and digestive enzymes. A diet that supports and helps prevent cancer, is made from fresh foods or home cooked foods. It is very important to have good nutrition in anticancer diets. Your dog's lifespan will increase enormously from a top quality diet. Thy food is thy medicine.
